Studies have shown that people heavily exposed to copper, lead, manganese, zinc, herbicides,and pesticides have a higher risk of developing PD than people not exposed. Another environmental toxin recently linked to Parkinson’s Disease is the synthetic drug MPTP. MPTP poisons the mitochondria, resulting in decreased energy production and cell death.
